 Wonder if you should get tested for colorectal cancer? Well, it's the second leading cancer killer in the U.S., so if you're 50 or older, it's time. Screening helps find precancerous polyps so they can be removed. Remove the polyp, prevent the cancer. Did you know there's more than one screening test? Talk to your doctor to find the one that's right for you. No more excuses, because colorectal cancer screening really does save lives. A message from HHS and CDC's Screen for Life campaign.
